Electromechanical rotary-blade cutter to sever flatpacks in pipe from 4 1/2 to 7 3/4 in.
Talk to an expertThe ClearCut® RB cutter uses the most advanced electromechanical cutting technology to sever tubing encapsulated cables (TEC) or flatpacks on the back of tubing or casing in a well. These cables can be single Inconel tubes or multiconfiguration electrical cables and Inconel tubes that support downhole sensors, electrical power, fiber optics, hydraulics, and chemical injection. The cables are encapsuled in a protective rectangle polyimide or similar sleeve to resist the aggressive downhole environment and are held in place with a clamp at each pipe joint. It is not uncommon for a well to contain two to five multi-pack flatpacks, and the cables must be cut before the pipe is fully severed.
The tool design includes a highefficiency brushless motor and bespoke controller with customized anchor setups. An indexed splitting blade from the machine tool industry is used to ensure the cutting inserts are not dulled prematurely when API 5 CRA (corrosion resistant alloys) pipe is severed, including 37% nickel and 27% chromium SM2535-125. The tool can pivot downhole from the traditional sweeping 360° cutting motion to a 45° petal or slot cut for pipe compression or high-nickel-alloy scenarios. The platform supports 3.625- and 4.85-in. cutting heads to provide industryleading blade extension at 8.134 in. with 1.15-in. thickness. The latter measurement determines how offset the flatpack can be from the pipe OD and still be successfully severed. The RB cutter can be run in combination with the Halliburton Freepoint Tool (HFPT) to perform multiple cuts in a single downhole deployment. This tool has no dangerous goods associated with the services and no requirement for an explosive escort. This helps facilitate efficient intervention with reduced HSE risk.
